Description

Data measurement method and device

[0001] This application claims priority to the Chinese patent application filed with the Intellectual Property Office of the People's Republic of China on December 4, 2023, with application number 202311652181.1 and application name "Method and Device for Data Measurement", the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a method and apparatus for data measurement. Background Art

[0003] In wireless network quality of service (QoS) monitoring, wireless network maintenance personnel need to manually obtain the flow identification information of the service data to be measured and manually control the start of flow measurement. After the communication equipment in the wireless network measures the service data, it reports the measurement results to the wireless network's network management equipment, which then determines the wireless network's QoS based on the measurement results. In bearer network QoS monitoring, bearer network maintenance personnel also need to manually obtain the flow identification information of the service data to be measured and manually control the start of flow measurement. After the communication equipment in the bearer network measures the service data, it reports the measurement results to the bearer network's network management equipment, which then determines the bearer network's QoS based on the measurement results.

[0004] When the transmission of business data needs to pass through wireless networks and bearer networks, due to the inconsistent encapsulation format and flow identifier definition of business data in wireless networks and bearer networks, different networks cannot communicate with each other, and therefore it is impossible to achieve end-to-end (device-to-device) automatic transmission measurement on wireless networks and bearer networks. Summary of the Invention

[0005] The present application provides a data measurement method and apparatus, which can implement end-to-end (device-to-device) automatic measurement on wireless networks and bearer networks.

[0006] On the first aspect, a method for data measurement is provided, which can be applied to a first transmission device in a bearer network. For example, it can be executed by the first transmission device, or it can be executed by a component configured in the first transmission device (such as a chip, a chip system, etc.), or it can be implemented by a logic module or software that can realize all or part of the functions of the first transmission device. This application does not limit this.

[0007] Exemplarily, the method includes: a first transmission device receives control information and service data, the control information includes at least one of first flow identification information, measurement mode information, measurement period information, or measurement type information of the service data, and the first flow identification information is the flow identification information of the service data in the wireless network; the first transmission device measures the service data according to the control information to obtain first measurement result information; the first transmission device sends the first measurement result information to the first network management device.

[0008] Based on the above technical solution, the wireless access network device or core network device in the wireless network can send control information for measuring service data to the transmission device (first transmission device) in the bearer network, and the transmission device in the bearer network can automatically measure the service data from the wireless network based on the control information. Compared with the transmission measurement solution in which wireless network maintenance personnel and bearer network maintenance personnel manually input flow identification information, the present application can realize end-to-end (device-to-device) automatic measurement on the wireless network and the bearer network.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: the first transmission device converts the first flow identification information into second flow identification information, the second flow identification information being the flow identification information of the service data in the bearer network, wherein the first measurement result information includes a mapping relationship between the first flow identification information and the second flow identification information.

[0010] Optionally, a unified network management device can assign unified flow identification information, and the flow identification information of service data in the wireless network and the bearer network is the same. In this optional solution, the first transmission device does not need to convert the flow identification information of the service data. The wireless access network equipment, core network equipment, and transmission equipment in the bearer network (including the first transmission device) can measure the service data based on this unified flow identification information. The unified network management device can be understood as a device that uniformly manages the network management equipment of the wireless network and the network management equipment of the bearer network.

[0011] With reference to the first aspect, in certain implementations of the first aspect, the measurement mode information indicates a packet-by-packet measurement mode or a sampling measurement mode.

[0012] In combination with the first aspect, in some implementations of the first aspect, the measurement type information indicates at least one of packet loss rate measurement, packet loss number measurement, delay measurement, throughput measurement, or jitter measurement.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the control information and the service data are carried in a user plane message.

[0014] In conjunction with the first aspect, in certain implementations of the first aspect, the control information is carried in an Internet Protocol (IP) extension header, a User Datagram Protocol (UDP) extension header, or a General Packet Radio Service User Tunneling Protocol (GTPU) extension header of the user plane message. In this implementation, after receiving the user plane message, the first transmission device performs a snooping operation on the user plane message to obtain the control information.

[0015] In conjunction with the first aspect, in certain implementations of the first aspect, the control information is carried in a control plane message, and the service data is carried in a user plane message. In this implementation, the control information and service data are sent to the first transmission device via different information / messages.

[0016] In conjunction with the first aspect, in certain implementations of the first aspect, the control information is carried in an IP extension header, a Transmission Control Protocol (TCP) extension header, a UDP extension header, or a GTPU extension header of the control plane message, and the destination address of the control plane message is address information of a radio access network device or a core network device.

[0018] In conjunction with the first aspect, in certain implementations of the first aspect, the control information is carried in an IP extension header or an IP message payload of the control plane message, and the destination address of the control plane message is the address information of the first transmission device. In this implementation, the radio access network device and the core network device do not send the control information via an extended existing message, but instead send the control information via a specific / newly constructed control plane message. Because the destination address of the control plane message is the address information of the first transmission device, after receiving the control plane message, the first transmission device can directly parse the control plane message to obtain the control information.

[0019] In combination with the first aspect, in some implementations of the first aspect, the control plane message includes an ICMP message, a TCP message, a UDP message, a Stream Control Transmission Protocol (SCTP) message, or other IP messages.

[0020] On the second aspect, a method for data measurement is provided, which can be applied to a wireless access network device or a core network device. For example, it can be executed by a wireless access network device or a core network device, or it can be executed by a component configured in the wireless access network device or the core network device (such as a chip, a chip system, etc.), or it can be implemented by a logic module or software that can realize all or part of the functions of the wireless access network device or the core network device. This application does not limit this.

[0021] The method includes: sending control information and service data to a first transmission device, the control information including at least one of flow identification information, measurement mode information, measurement period information, or measurement type information of the service data, the control information being used to control at least one transmission device in a bearer network to measure the service data, the at least one transmission device including the first transmission device; and sending second measurement result information to a second network management device, the second measurement result information being obtained by measuring the service data based on the control information.

[0063] In order to facilitate understanding of the technical solutions of the embodiments of the present application, before introducing the solutions of the embodiments of the present application, the terms or concepts that may be involved in the embodiments of the present application are first introduced.

[0064] 1. Protocol Data Unit (PDU) session: A logical connection between a terminal device and a data network (DN), used to provide the terminal device with a user plane connection to the DN.

[0065] 2. Bearer network: The bearer network is the basic network that provides network connectivity for the radio access network (wireless network) and the core network. It consists of access routers, edge routers, and core routers. To meet the needs of 5G application scenarios, the 5G bearer network continues to evolve towards large bandwidth, low latency, network slicing, and intelligence, providing 5G networks with ultra-large bandwidth, ultra-low latency, flexible and intelligent connection services.

[0066] To facilitate understanding of the embodiments of the present application, the following briefly introduces the technical solutions related to the embodiments of the present application.

[0067] 1. Wireless Network Measurement Technology

[0068] FIG2 is a schematic flow chart of a QoS monitoring solution in a wireless network, and the specific process is as follows.

[0069] 1. Manually issue a man-machine language (MML) command in the SMF to start slice monitoring; the SMF adds an MML configuration, which includes a slice identifier (ID), a maximum number of sessions, and measurement start / measurement stop. The slice ID indicates which services of which slices are measured, the maximum number of sessions indicates the specifications of the measured services, the measurement start indicates when to start measurement, and the measurement stop indicates when to stop measurement.

[0070] 2. Manually start the key performance indicator (KPI) statistics of the traffic statistics in the element management system (EMS).

[0071] 3. The SMF samples based on the number of users in the slice and initiates latency monitoring when a session is created. Specifically, the response message sent by the AMF to the base station during session creation includes an indication to initiate latency monitoring. The SMF manages latency monitoring for Quality of Service (QoS) flows and assesses the impact of QoS flow latency on system memory.

[0072] Among them, the network slice subnet management function (NSSMF) on the core network (CN) sends the maximum number of sessions of the slice to SMF, and SMF needs to calculate it into the number of QoS flows according to the product's default traffic model.

[0073] 4. SMF controls UPF to enable latency monitoring. For example, when there are fewer slices, sampling can be fixed at 1%, and the minimum number of users can be limited, for example, the number of users cannot be less than 10.

[0074] 5. The base station starts sampling the air interface delay.

[0075] 6. The base station calculates the air interface delay between the base station and the terminal device, such as uplink delay X1 / downlink delay X2.

[0076] 7. UPF starts sampling. The GTPU packet header carries a QoS monitoring packet (QMP) tag. UPF can sample at a rate of 1 packet / 10ms. The sampling specification on UPF cannot exceed 1% of the QoS flow number specification.

[0077] 8. The base station reports delay statistics to the UPF;

[0078] 9. UPF calculates round trip time (RTT) = X1 + X2 + (t6 - t1) - (t5 - t2);

[0079] 10. UPF generates the average delay, minimum delay, maximum delay and statistical times of base station-UPF / terminal equipment-UPF according to the statistical period of the call statistics (for example, 5 minutes / 15 minutes), and reports the delay statistical results to EMS.

[0080] 11. EMS reports latency statistics to CN NSSMF, which implements performance statistics and monitoring of slice-level latency KPIs.

[0081] 2. Bearer Network Measurement Technology

[0082] Figure 3 is a schematic diagram of a flow measurement solution in a bearer network. The flow measurement process for a bearer network-initiated service flow includes:

[0083] 1. The ingress device initiates hop-by-hop detection of the service flow and periodically reports measurement data (measurement result information) such as packet loss rate, latency, and jitter to the network management device of the bearer network. The ingress device is understood to be the head node connected to the radio access network device in the bearer network. The network management device of the bearer network can be the network cloud engine (NCE);

[0084] 2. The transit device initiates hop-by-hop detection of the service flow and periodically reports measurement data such as packet loss rate, latency, and jitter to the network management device of the bearer network;

[0085] 3. The egress device initiates hop-by-hop detection of the service flow and periodically reports measurement data such as packet loss rate, latency, and jitter to the network management device of the bearer network;

[0086] 4. The network management equipment collects the measurement data reported by the ingress, intermediate, and egress devices in the bearer network, and performs segmented calculations to present the packet loss rate, latency, and jitter of each device (node) / link in the bearer network, facilitating troubleshooting by operation and maintenance personnel.

[0087] Here, ETH refers to Ethernet, and MPLS LABEL refers to multi-protocol label switching. It should be noted that the ingress device, intermediate device, and egress device in the embodiments of the present application can be collectively referred to as transmission devices, bearer devices, bearer nodes, or gateway devices, without limitation.

[0088] 3. End-to-end measurement technology on wireless networks and bearer networks

[0089] Figure 4 is a schematic diagram of end-to-end transmission measurement on wireless networks and bearer networks. The specific process includes:

[0090] 1. The AMF controls the terminal device, base station, and UPF to start QoS monitoring and uniformly reports the measurement data to the network management device of the wireless network, where the network management device of the wireless network can be the EMS;

[0091] 2. The wireless network maintenance personnel manually obtains the flow identification information to be measured and informs the bearer network maintenance personnel. The bearer network maintenance personnel manually inputs the flow identification information and controls the transmission equipment in the bearer network to start hop-by-hop flow detection of the service flow. The transmission equipment in the bearer network reports the measurement data to the bearer network network management equipment, where the bearer network network management equipment can be the NCE.

[0092] 3. If the flow identification information to be measured changes, repeat step 2.

[0093] Since the encapsulation format and flow identifier definitions of service data in wireless networks and bearer networks are inconsistent, different networks cannot communicate with each other, making it impossible to implement end-to-end automatic transmission measurement on wireless networks and bearer networks.

[0094] To this end, an embodiment of the present application proposes a data measurement method, which can implement end-to-end (device-to-device) automatic measurement on a wireless network and a bearer network.

[0095] Figure 5 is a schematic flow chart of a data measurement method 500 according to an embodiment of the present application. In the embodiment of the present application, the first transmission device may be an ingress device or an egress device in the bearer network, the wireless access network device may be a base station, the core network device may be a UPF, and the terminal device may be a UE.

[0096] At step 510, a radio access network device or a core network device sends control information and service data to a first transmission device. The control information includes at least one of first flow identification information, measurement mode information, measurement period information, or measurement type information of the service data. The first flow identification information is flow identification information of the service data in the wireless network. Correspondingly, the first transmission device receives the control information and service data. The control information is used to control at least one transmission device in the bearer network to measure the service data. The at least one transmission device includes the first transmission device.

[0097] In an exemplary embodiment, a wireless access network device sends control information and service data to a first transmission device; correspondingly, the first transmission device receives control information and service data from the wireless access network device. The first transmission device is an ingress device in the bearer network. This example illustrates uplink transmission of service data.

[0098] Exemplarily, a core network device sends control information and service data to a first transmission device; correspondingly, the first transmission device receives control information and service data from the core network device. The first transmission device is an egress device in the bearer network. This example illustrates downlink transmission of service data.

[0099] Optionally, the measurement mode information indicates a packet-by-packet measurement mode or a sampling measurement mode.

[0100] Optionally, the measurement type information indicates at least one of packet loss rate measurement, packet loss number measurement, delay measurement, throughput measurement, or jitter measurement.

[0101] Optionally, the control information and service data are carried in user plane messages.

[0102] In one implementation, the control information is carried in an IP extension header, a UDP extension header, or a GTPU extension header of a user plane message. In this implementation, after receiving the user plane message, the first transmission device performs a snooping operation on the user plane message to obtain the control information.

[0103] For example, taking a GTPU user plane service message as an example, an IP extension header is added to the GTPU user plane service message. Control information is carried in this newly added IP extension header, and this control information is sent to the first transmission device along with the service data. Figure 6 shows a schematic diagram of adding an IP extension header to a GTPU user plane service message. The left side corresponds to the IPv4 header format, and the right side corresponds to the IPv6 header format. IHL stands for Internet Header Length.

[0104] For another example, taking a GTPU user plane service message as an example, a UDP extension header is added to the GTPU user plane service message, and control information is carried in the added UDP extension header. This control information is then sent to the first transmission device along with the service data. Figure 7 illustrates adding a UDP extension header to a GTPU user plane service message; specifically, a magic number (probe marker) and a UDP extended measurement header are added after the UDP header.

[0105] Optionally, the control information is carried in a control plane message, and the service data is carried in a user plane message. In this optional solution, the control information and the service data are sent to the first transmission device via different information / messages.

[0106] In one implementation, control information is carried in an IP extension header, a Transmission Control Protocol (TCP) extension header, a UDP extension header, or a GTPU extension header of a control plane message. The destination address of the control plane message is the address information of a radio access network device or a core network device. Specifically, when the first transmission device is an ingress device in the bearer network / for uplink transmission, the destination address of the control plane message is the address information of the core network device; when the first transmission device is an egress device in the bearer network / for downlink transmission, the destination address of the control plane message is the address information of the radio access network device. In this implementation, after receiving the control plane message, the first transmission device performs a sniffing operation on the control plane message to obtain the control information.

[0107] Illustratively, the control plane message includes a GTPU ECHO message, an Internet Control Message Protocol (ICMP) message, a Two Way Active Measurement Protocol (TWAMP) message, or a UDP message. The control plane message may also include other existing control plane messages, which are not limited in this application.

[0108] For example, taking the control plane message as a GTPU ECHO message, a GTPU extension header is added to the GTPU ECHO message, and the control information is carried in the added GTPU extension header. Figure 8 is a schematic diagram of adding a GTPU extension header to the GTPU ECHO message.

[0109] In one implementation, the control information is carried in an IP extension header or IP message payload of a control plane message. The destination address of the control plane message is the address information of the first transmission device. In this implementation, the radio access network device and the core network device do not send the control information via an extended existing message, but instead send the control information via a specific / newly constructed control plane message. Because the destination address of the control plane message is the address information of the first transmission device, upon receiving the control plane message, the first transmission device can directly parse the control plane message to obtain the control information.

[0110] Illustratively, the control plane message includes an ICMP message, a TCP message, a UDP message, a stream control transmission protocol (SCTP) message, or other IP messages. For example, if the control plane message is an IP message, the control information can be carried in an IP extension header or an IP message payload. The control plane message can also be any other specific or newly constructed control plane message, which is not limited in this application.

[0111] Optionally, before the wireless access network device or the core network device sends control information and service data to the first transmission device, the AMF controls the terminal device, the wireless access network device, and the core network device in the wireless network to start QoS monitoring, and uniformly reports the respective measurement result information to the core network device. The flow identification information of the service data in the wireless network may include: a tunnel endpoint identifier (TEID), a quality of service flow identifier (QoS flow identifier), a flow protocol type of the service data, a protocol port number of the wireless access network device, a protocol port number of the core network device, an IP address of the wireless access network device, an IP address of the core network device, or an IPv6 flow label (flow label) of the wireless access network device.

[0112] At 520, the first transmission device measures the service data according to the control information to obtain first measurement result information. For example, the first transmission device performs in-situ flow information telemetry (iFiT), in-band operation administration and maintenance (IOAM), or other flow measurement methods on the service data according to the control information to obtain the first measurement result information.

[0113] Optionally, before the first transmission device measures the service data according to the control information, the first transmission device converts the first flow identification information into second flow identification information, and saves the mapping relationship between the first flow identification information and the second flow identification information, where the second flow identification information is the flow identification information of the service data in the bearer network; the first measurement result information includes the mapping relationship between the first flow identification information and the second flow identification information.

[0114] Optionally, a unified network management device can assign unified flow identification information, and the flow identification information of service data in the wireless network and the bearer network is the same. In this optional solution, the first transmission device does not need to convert the flow identification information of the service data. The wireless access network equipment, core network equipment, and transmission equipment in the bearer network (including the first transmission device) can measure the service data based on this unified flow identification information. The unified network management device can be understood as a device that uniformly manages the network management equipment of the wireless network and the network management equipment of the bearer network.

[0115] 530. The first transmission device sends first measurement result information to the first network management device. Correspondingly, the first network management device receives the first measurement result information.

[0116] It should be noted that the transmission devices in the bearer network measure the service data according to the control information and send respective first measurement result information to the first network management device; the first network management device receives the first measurement result information corresponding to each transmission device.

[0117] At 540, the radio access network device and the core network device each send second measurement result information to the second network management device. The second measurement result information is obtained by measuring the service data based on the control information. Exemplarily, the radio access network device measures the service data based on the control information to obtain the second measurement result information, and sends the second measurement result information to the second network management device. The core network device measures the service data based on the control information to obtain the second measurement result information, and sends the second measurement result information to the second network management device. Correspondingly, the second network management device receives the second measurement result information sent respectively by the radio access network device and the core network device in the wireless network. In this embodiment of the present application, the network management devices of the wireless network may be collectively referred to as the second network management device. For example, the network management devices of the radio access network device and the core network device may be collectively referred to as the second network management device.

[0118] Optionally, the terminal device measures the service data according to the control information, obtains second measurement result information, and sends the second measurement result information obtained by the terminal device to the wireless access network device; the wireless access network device can report the second measurement result information obtained by the terminal device directly to the network management device of the wireless access network device, and the wireless access network device can also report the second measurement result information obtained by the terminal device to the core network device, and the core network device reports it to the network management device of the core network device.

[0119] Among them, step 540 can be executed before step 510, and step 540 can be executed at any time between step 510 and step 530, which is not limited in the embodiment of the present application.

[0120] In the technical solution provided in the embodiments of the present application, a wireless access network device or a core network device in a wireless network can send control information for measuring service data to a transmission device (first transmission device) in a bearer network, and the transmission device in the bearer network can automatically measure the service data from the wireless network based on the control information. Compared to the transmission measurement solution in which wireless network maintenance personnel and bearer network maintenance personnel manually input flow identification information, the present application can achieve end-to-end (device-to-device) automatic measurement on wireless networks and bearer networks.

[0121] Optionally, the first network management device is a network management device of a bearer network, for example, the first network management device is an NCE; the second network management device is a network management device of a wireless network, for example, the second network management device is an EMS. Optionally, the first network management device sends first measurement result information to a unified network management device, and the second network management device sends second measurement result information to the unified network management device; correspondingly, the unified network management device receives the first measurement result information and the second measurement result information, and determines at least one of the packet loss rate, latency, throughput, or jitter of the service data on the transmission path based on the first measurement result information and the second measurement result information. The transmission path of the service data includes: terminal device → wireless access network device → transmission device in the bearer network (for example, the first transmission device) → core network device, or, core network device → transmission device in the bearer network (for example, the first transmission device) → wireless access network device → terminal device.

[0122] Optionally, the first network management device and the second network management device are the same network management device. For example, the first network management device is the unified network management device described above, and the unified network management device determines at least one of a packet loss rate, a delay, a throughput, or a jitter of the service data on the transmission path based on the first measurement result information and the second measurement result information.

[0123] The data measurement method provided by the embodiment of the present application is described below with reference to a specific example. In this example, the transmission path of service data is as follows: terminal device → wireless access network device → transmission device in the bearer network (e.g., first transmission device) → core network device.

[0124] Step 1: AMF controls the terminal devices, wireless access network devices and core network devices in the wireless network to start QoS monitoring, and uniformly reports their respective measurement results to the core network devices.

[0125] Step 2: The wireless access network device in the wireless network initiates measurement of service data whose flow identification information is the first flow identification information, and obtains second measurement result information; wherein, the wireless access network device measures the service data in a packet-by-packet measurement manner or a sampling measurement manner, the measured parameter or type is at least one of packet loss rate, delay, throughput, or jitter, and the measurement period is T.

[0126] It should be noted that the terminal device and the core network device in the wireless network will also start measuring the service data whose flow identification information is the first flow identification information, and obtain respective second measurement result information.

[0127] Step 3: The wireless access network device sends control information and service data to the first transmission device in the bearer network. The control information includes first flow identification information, measurement mode information, measurement period information, and measurement type information of the service data, wherein the measurement mode information indicates a packet-by-packet measurement mode or a sampling measurement mode, the measurement period information indicates that the measurement period is T, and the measurement type information indicates at least one of packet loss rate measurement, packet loss number measurement, delay measurement, throughput measurement, or jitter measurement. The first transmission device is an ingress device in the bearer network; correspondingly, the first transmission device receives the control information and service data from the wireless access network device.

[0128] Step 4: The first transmission device converts the first flow identification information into second flow identification information and saves the mapping relationship between the first flow identification information and the second flow identification information. The second flow identification information is the flow identification information of the service data in the bearer network.

[0129] Step 5: The first transmission device measures the service data based on the control information to obtain first measurement result information. Exemplarily, the first transmission device performs in-stream detection, IOAM, or other flow measurement on the service data based on the control information to obtain the first measurement result information. The first measurement result information includes a mapping relationship between the first flow identification information and the second flow identification information.

[0130] It should be noted that the transmission equipment in the bearer network will measure the service data according to the control information to obtain first measurement result information of each measurement.

[0131] Step 6: The transmission devices in the bearer network each send their respective first measurement result information to a first network management device. Accordingly, the first network management device receives the first measurement result information. The first network management device is the network management device of the bearer network, for example, the first network management device is an NCE. The radio access network device and the core network device in the wireless network each send their respective second measurement result information to a second network management device. Accordingly, the second network management device receives the second measurement result information. The network management devices of the wireless network can be collectively referred to as second network management devices. For example, the network management devices of the radio access network devices and the core network devices can be collectively referred to as second network management devices.

[0132] Optionally, the terminal device measures the service data according to the control information, obtains second measurement result information, and sends the second measurement result information obtained by the terminal device to the wireless access network device; the wireless access network device can report the second measurement result information obtained by the terminal device directly to the network management device of the wireless access network device, and the wireless access network device can also report the second measurement result information obtained by the terminal device to the core network device, and the core network device reports it to the network management device of the core network device.

[0133] Step 7: The first network management device sends the first measurement result information to the unified network management device (or third-party service device), and the second network management device sends the second measurement result information to the unified network management device (or third-party service device). The unified network management device (or third-party service device) can be understood as a device that uniformly manages the wireless network and the bearer network. Correspondingly, the unified network management device receives the first measurement result information from the first network management device and the second measurement result information from the second network management device.

[0134] Step 8: The unified network management device (or third-party service device) determines at least one of the packet loss rate, delay, throughput, or jitter of the service data on the transmission path based on the first measurement result information and the second measurement result information.
